IMPROVEMENT IN HARVESTERS.

\ speaiaton armingparn iofLeaei-S Patent No. 112,288, dma February 2s, 1871.

`@To all whom itmayloncem: I Be it known thatI, J ,icons W ScHUoImRS, f of the city and countyof Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in Harvesters, of

\ which the-following is a specification:

My inventionrelates to a novel method of connecting the pitman and cutters in twoguidewa'y in Said frame, and a link-rod pivoted `both to the pitman and cutter-bar, as herein` e after described.`

My improvements are to be used in a fullyorganized harvesting-machine. In the accom-` panyingdrawing,however, I have shown so much only of the mechanism as illustrates the "invention herein claimed, the construction of I the other parts being well understood by skilly ful builders of harvesting machinery.

i Ifigurel` represents a plan; Fig.` 2, a side `j elevatioirofthe machine; and Fig. 3, an enlarged guide.

view,l in perspective, of the pitman- The driving-wheels `A A are mounted on an axle, B, which carries a main frame, C. The tongue D projects from the front of the frame.

A finger-beam, E,Iis secured fto a shoe, E',

having lugs' upon it, by means of which it is y or arm, F the upper end of which is swiveled to the under side of the frame at f. A bracebar, G, is pivoted at one end to the frame,and

at the other to the coupling-arm.

A crank-shaft, N, driven by proper gearing,

I operates the pitman P, the lower end of which carries a pin, l, or cross-head, which slides in a groove. A link-rod, p, is pivoted at one end to this pitman, and at the other to the cutterbar B. i

By this mode of construction the pitman always reciprocates in a uniform path, while the link-rod p swings around its pivoted connection with the pitman in conformity with the swinging of the finger-beam around its pivots e, and the cutters will continue to run without ,I binding at any inclination to which the outer end of the linger-beam can be raised or lowered in running over imeven ground.

Iclaim'y as my invention- The combination of the coupling-frame, the nger-beam hinged thereto, the pitm an work- `ing in a guide in the coupling-frame, the cut- ;trbar, and the link-rodfpivoted both to the pitman and cutter-bar, allthese parts being constructed and operating as described, to insure theworking of the cutters at varying inclinations of the linger-beam, as set forth.

In testimony whereof I have hereunto subscribed my name.
